- spaces will be left between Patented Dec. 5, 1933 MACHINE FOR CUTTINGAND SHAPING CAKES AND BISCUITS Theodoor Renier Application Neutelings,Bergen-op-Zoom, Netherlands August 29, 1931, Serial No. 560,160, 6 inBelgium August 29, 1930 1 Claim. (01. 107-23) leaving scrap or at leaminimum.

st reducing said scrap to a The invention aims to cut and shaperectangular or square biscuits and cakes without producing scrap,

whereas fancy shapes, such as oval or like biscuits will be cut andformed with a minimum of scrap.

In machines of this the sheet of dough by means kind it is usual toshape of a die roller in cooperation with a pressure roller, the sheetof dough being conveyed between said rollers by means of an endlessconveyor.

The dies of the die roller are separated from each other by free spaceswhich obviously leave a net of scrap to be continuously removed ing theshaped biscuits,

for the purpose'of conveyduly separated, upon subsequent aprons towardsthe oven.

In conformity with of rectangular biscuits the invention, in the case orcakes, no scrap forming the dies of the shaping roller, whereas forfancy shapes, the dies will be arranged in annular series and suchseries will another, so that during upon the die roller, be arrangedclose to one the shaping of the biscuits, only narrow strips of scrapwill be left between the successive of scrap will be easily shapedbiscuits either The invention series of dies. Such strips removed frombetween the manually or mechanically.

furthermore provides for means to arrange the biscuits or cakes dulyseparated from each other upon the shaped pieces of d convenient orderlya conveying band, sothat ough will be delivered in a manner to thebaking oven.

In the manufacture of rectangular biscuits without leaving scrap, haveto be separated the shaped pieces of dough from each other as well inthe longitudinal as in the transverse direction with respect to themachine.

The separation in the longitudinal direction of the shaped cakes isperformed by means of a conveying apron,

the

speed of which is higher than that of the conveyor upon which thebiscuits are shaped, and when the cakes are progressing in-rowsseparated from each other over a short distance; separation of theshaped cakes transverse direction with respect to the machine, byconveying the rows upon upon which the dough shaped arrangementmovement, so as to be -other in the transverse shaped conveyor to b willbe performed in the a particular apron, pieces will spread in afanduring their progressing come separated from each direction. Fromthis fane described hereafter, the

cakes are brought upona baking sheet engaging the oven.

In the manufacture of fancy shapes, for instance oval or circular cakes,the intermediate strips of scrap which will be of reduced dimen- 69sions have to be' lifted and removed, whereas the cakes will beseparated from each other at their contacting heads by means of aconveying band having a higher speed.

The machine will be described hereafter with reference to theaccompanying drawing. In the drawing:

Fig. 1 is a diagrammatic side elevation of the machine constructedaccording to the invention, the back side of the frame with drivinggears being only shown;

Fig. 2 is a plan view of a fan-shaped conveyor;

Fig. 3 is a plan view of a die roller for shaping rectangular biscuits;

Fig. 4 is a plan view of a new die roller for manufacturing ovalbiscuits in conformity with the invention.

With reference to Fig. 1, it is known in such machines to have the doughrolled in a sheet of appropriate thickness, suchsheets being conveyed byan endless conveyorl between the die roller 2a'nd the pressure roller 3,such pressure roller being for instance'coated with a layer of rubber.The axes of both rollers are deviated from each other over an angle ofabout 5 with respect to the running direction of the conveying band 1,so that the tension of the conveyor cooperates with the pressure of therollers upon each other to convey the sheet of dough nearly in alongitudinal direction between said rollers. The machine has a frame 25mainly formed with lateral upright members supporting the rollers anddriving means. The driving means of the die roller are variable and mayfor instance comprise a toothed gear 26, and such die rollers areinterchangeable so that for instance biscuits can be shaped by means ofrollersthe diameter of which varies between 3 and 3.55 inches, whereasin the case of cakes made from consistent dough, 10' die rollers having7.8 to 15.7 inches of diameter can be used. It is obvious'that therotation of the die rollers. will be varied according to the variablediameters. I

The conveyor 1 brings the shaped cakes over 10.- a guidingplate 5 fromwhich said conveyor is guided over a roller 6 to pass again overitsusual driving rollers.

An endless apron '7, made for instance from a net of wire is runningover rollers 10 and 11 114 ind and is passing over a roller 8 whichconveniently constitutes a driving roller for said apron, and which isarranged close to the guiding plate 5,- so that the shaped cakes will bebrought from the conveying band 1 upon the conveying apron 7. Roller 8is conveniently driven by the set of toothed gears 26, 27, 28 and 29,journalled in the upright frame member 25.

Owing to the weight of the conveyor 7 and its elasticity, this conveyorbends somewhat downwards over the roller 8, so that at this place theshaped pieces of dough have a crack imparted thereto in the transversedirection of the machine, so as to complete the break which started'under the action of the die roller cutting the sheet of dough insuccessive rows of shaped cakes. The conveyor 7 has a somewhat higherspeed, i. e. 29% higher than that of the conveyor 3., that thelongitudinal rows of shaped cakes will he arranged upon the conveyor 7in separated rows. For aforesaid operations it is 1y ecessary a dieroller 2, means i e cakes or biscuits are shaped for side scrap,

lie roller: (see 3) provided moulds, rectangular moulds 22, which areonly separated from each other by cutting edges Such imp oved die rollersecures a greater output and means economy of dough, and alsoconsiderably reduces waste in the form of badly moulded or brokenbiscuits or cakes.

hie conveyor 2'" will bring the separated rows of cakes close theconveyor wh ch ided over rollers 12, an l5; roller 5* is driven a chainwheel 30' and an endless chain running over another chain wheel with 23.conveyor 13 adapted the of separating the biscuits cakes in a nsversedirection; it will therefore of ticular construction to convey the cakesor lscuits a spreading or fan-shaped arrangem nt.

ith reference to 2, the conveyor is constituted by means of aconsiderable number of small endless strips of rubber or of strips ofperforated wire, said strips being guided in grooves provided on therollers 12 and 14. The number of grooves for Tooth rollers is the same,but the grooves of roller 14 are separated form each other by a somewhatgreater distance than is the case for the grooves of roller 12. Fromthis results that-the different strips are spreading from each other intheir progressing direction, although running at the same speed, and thesmall difference in length which occurs between the different conveyingstrips is compensated by the nature of the material'used, the stripsbeing made of rubber or perforated wire. It is obvlous that the shapedcakes will follow the "spreading action of this conveyor, so that theywill become separated from each other at their out portions. The soseparated biscuits will he brought by the conveyor 13 upon the bakingplate '16. This baking plate 16 is running over the drum 1'? and conveysthe biscuits or 'cakes' throughout the baking oven.

The conveyor 13 can obviously be made with a number-of bands or stripscorresponding to the number of cakes shaped with relation to thetransverse direction of the machine.

For the manufacture of cakes of fancy shape, such as for instance ovalcakes 29 (Fig. l), the best arrangement will be secured for instance byproviding rings of dies 20 separated by free spaces 21, these diesleaving a continuous side scrap, which is more easily removable than soparated pieces of scrap, which are for instance left in the case of diescontacting each other Ls both transverse and longitudinal directions.
